DUPONT PE827 - Global Headquarters

1 PRODUCT DESCRIPTIONDuPont PE827 is a very low temperature drying Silver Composite Conductor. PE827 has been designed to maintain low temperature substrate tolerances as this composition can be processed between 60 C-100 C. When dried using these low temperatures, PE827 has a unique ability to achieve very good physical and electrical properties. PE827 is a more economical version of BENEFITS Very low temperature drying Best thermal cure achieved between 60-100 C Excellent adhesion to a variety of substrates Compatible/blendable with PE828 for desired resistivityPROCESSINGS creen Printing Equipment Automatic reel-to-reel Semi-automatic flat-bedSubstrates Polycarbonate PVC Acrylic Polyester Film Polystyrene PVDFS creens Stainless steel mesh - 325 230 wire/inch (SD 50/30-SD 75/36)

2 Polyester mesh - 90-40 to 61-64 thread/cmDryingFor best conductivity, dry at 60 C 100 C in a well-ventilated box/static oven for 10 20 minutes Conveyorised/tunnel ovens tend to be more efficient and drying times will be shorter. Drying efficiency, and print quality/thickness help insure best electrical and physical performance.
